MAX5811 General Description

The MAX5811 is a single, 10-bit voltage-output digital-toanalog converter (DAC) with an I²C™-compatible 2-wire interface that operates at clock rates up to 400kHz. The device operates from a single 2.7V to 5.5V supply and draws only 100A at V_DD= 3.6V. A low-power powerdown mode decreases current consumption to less than 1A. The MAX5811 features three software-selectable power-down output impedances: 100k, 1k, and high impedance. Other features include an internal precision Rail-to-Rail^® output buffer and a power-on reset (POR) circuit that powers up the DAC in the 100k power-down mode.

The MAX5811 features a double-buffered I²C-compatible serial interface that allows multiple devices to share a single bus. All logic inputs are CMOS-logic compatible and buffered with Schmitt triggers, allowing direct interfacing to optocoupled and transformer-isolated interfaces. The MAX5811 minimizes digital noise feedthrough by disconnecting the clock (SCL) signal from the rest of the device when an address mismatch is detected.

The MAX5811 is specified over the extended temperature range of -40 to +85 and is available in a space-saving 6-pin SOT23 package. Refer to the MAX5812 data sheet for the 12-bit version.
